it is desired to change the setting of the fan, it is only necessar Y to loosen -the wing nut 8, thereby releasing the various parts of the device, after which the fan may be adjusted to any desired position and. inclination .by virtue of the peculiarities of the adjustable joint hereinbefore described.

While I have shown and described a device of specific construction and arrangement and location of parts, it is evident that various modifications may be effected without departing from the spirit and scope of my invention, and I desire that only such limitations shall be imposed as are indicated in the appended claims. 4

I claim as my invention: 1. The combination with a member having a plurality of substantially parallel arms, a

- second member pivotally mounted between said arms and having a cylindrical recess therein substantially normal to its pivotal support, and stem rotatably set in said recess, of means for clamping said parts together and'means for preventing longitudinal movement of said stem.

2. The combination with a member having upwardly projecting side port-ions, a second disk-like member having a central open ng therein disposed between said portions. and

i a third member rotatably mounted in the opening therethrough,

opening of said second member, of a relatively large pin projecting through said side portions and constituting a pivotal support for said disk-like member, and having a transverse opening therein to receive said third member and means for clamping said parts together. 1

3. The combination with a supporting member having parallel arms, a pin projecting therethrough and having a transverse opening of relatively small diameter therein, a second member pivotally mounted on said pin in intimate contact with said arms and having a recess to register'with the transverse opening in said pin, anda stem rotatably disposed. in said recessan'd projecting through said transverse opening in said pin, of clamping means associated with one end of said pin for locking the parts firmly together, and means associated with the opposite end thereof for preventing longitudinal movement of said stem.

at. The combination with a U-shaped member, a pin extending through the side portions thereof and having a transverse a second member pivotally mounted on said pin intermediate the side portions of said U-shaped member,. said second member being prbvided with a recess disposed normally to said pin and registering ivith the transverse opening in said pin, and a cylindrical stem rotatably disposed in said recess and projecting through said transverse opening, of a single means for clamping all said parts together.

5. The combination with a U shaped member having parallelly disposed side portions, a disk member located between said side portions and having a cylindrical recess therein, a pin extending through said side portions upon which; said disk member is pivotally mounted, said pin having a transverse opening of relatively small diameter to register with the recess in said disk member, and a stem rotatably disposed in said recess and projecting through the transverse opening in said'pin, of clamping means associated 1n position. a V

6. The combination with a member having a plurality of substantially parallel arms and a second member pivotally supported between the said arms, of a stem associated with the said pivotally supported member, a body pivotally secured to the said pivotally supported member by means of the said stem, and means for clamping the said pivotally supported member between the said parallel arms.

7. The combination with a member having a plurality of substantially parallel arms and a second member pivotally supported between the said arms, of a stem associated with the said pivotally sup orted member, a body pivotally secured to the said pivotally supported member by means of the said stem, means for clamping the said pivotally supported member between the said parallel arms, and means for preventing disengagement between the said body and the said pivotally supported member.

8. The combination with a member having a plurality of substantially parallel arms and a second member pivotally supported bet-ween the said arms, of a-stem associated with the said pivotally supported member, a body pivot-ally secured to the said pivotally supported member by means of the said stem, means for clamping the said ivotally supported member between the said parallel arms, and means for preventing disengagement between the said body'and the said pivotally supported member, comprising an annular groove fern in the sat stem and a retaining screw cooperating n the said groove.
